A4988 Stepper Motor Driver

Availability: 12 In Stock
  • This product is a breakout board for Allegro's A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection;
  • This stepper motor driver lets you to operate bipolar stepper motors in full-, half-, quarter-, eighth-,
    and sixteenth-step modes, with an output drive capacity of up to 35 V and 2 A.
  • The translator is the key to the easy implementation of the A4988.
  • Simply inputting one pulse on the STEP input drives the motor one microstep.
  • There are no phase sequence tables, high frequency control lines, or complex interfaces to program.
  • The A4988 interface is an ideal fit for applications where a complex microprocessor is unavailable or is overburdened.
  • Features
  • Simple step and direction control interface
  • Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
  • Adjustable current control lets you set the maximum current output with a potentiometer,
    which lets you use voltages above your stepper motor's rated voltage to achieve higher step rates
  • Intelligent chopping control that automatically selects the correct current decay mode
    (fast decay or slow decay)
  • Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
  • Short-to-ground and shorted-load protection
  • Manufacturer: Open Hardware
